Definitions

  • the present invention relates to a temporary, relocatable, sports pitch assembly.
  • the present invention also relates to a method of assembling a temporary, relocatable, sports pitch assembly.
  • the temporary, relocatable, sports pitch assembly and method of the present invention are suitable for the provision of a temporary sports pitch capable of being used for professional sporting events. It may also be used for other activities that could be held on a sports pitch - e.g. other games or events.
  • stadiums of appropriate capacity may not be available for some sports, or newly-built stadiums may not have been provided with a permanent pitch yet.
  • pop up stadiums have become more widely used in recent years, due to space constraints in larger cities and the temporary need for larger stadiums in smaller cities and for‘one off’ major events.
  • a temporary, relocatable, sports pitch assembly which may be placed into an existing stadium which is configured to host other sports, into a newly-built stadium which has not been provided with a pitch yet, or into“pop-up” stadiums. It is further desirable that such a temporary, relocatable, sports pitch is of sufficient quality to host professional sports matches in any weather/climatic condition, and for it to be relocatable multiple times while maintaining the same quality.
  • the inventors have appreciated a need to minimise any damage caused to the surface on which the temporary sports, relocatable, pitch assembly is installed.
  • geotextile or geogrid layer is used to refer to permeable fabrics or geosynthetic materials used to reinforce soils. They are commonly made of polymers, and can be woven, punched, or bonded. They act to filter, reinforce, protect, or drain the soils.
  • the term“sport” or“sports” is used to refer to any activity involving physical exertion and/or skill in which individuals and/or teams compete against others, in particular any such activity performed on grass or which may be performed on grass.
  • the term“sports” does not only refer to organised team sports such as football, rugby, cricket, lacrosse, and hockey etc.
  • the temporary, relocatable, sports pitch assembly may also serve as a ground covering for other sports such as a temporary, relocatable, bowling green, or track etc.

  • each element of each layer allows for each element to be easily stackable or Tollable, which facilitates storage and portability.
  • the temporary, relocatable, sports pitch assembly may enable reconfiguration of the playing surface in a stadium, allowing for greater opportunity and flexibility to host a variety of sports, in particular those which do not have access to stadiums with a range of capacities. This may provide improved scope for a sport, such as hockey, to grow commercially through enabling existing stadiums normally designated for one particular sport (e.g. football / soccer) to enable use of their facilities and infrastructure to host games of another support (e.g. hockey).
  • a sport such as hockey
  • the at least one playing surface element coupling device is a temporary seam.
  • a temporary seam or tack may take any form of temporary stitching intended to be removed when adjacent playing surface elements are to be uncoupled. Such a temporary seam may provide sufficient support to oppose lateral movement of adjacent playing surface elements relative to one another, but may also be easily removable and installed.
  • the at least one playing surface element coupling device may be a hook-and- loop fastener.
  • a hook-and-loop fastener may comprise a plurality of hooks on a first part and loops on a second part. Said first part may be attached to one of a pair of adjacent playing surface elements, and said second part may be attach to the other one of a pair of adjacent playing surface elements. Hook-and-loop fasteners may easily be provided for each playing surface element, provide sufficient support to oppose horizontal movement of adjacent playing surface elements relative to one another, and allow for adjacent playing surface elements to be easily uncoupled. Further, hook-and-loop fasteners may be used repeatedly.
  • Hook-and-loop fasteners may be provided in very thin strips on the bottom side of the playing surface elements.
  • the temporary, relocatable, sports pitch assembly comprises fixing or gripping means for opposing horizontal movement of the playing surface layer relative to the shock absorbing layer.

  • the gripping / fixing means may ensure that the playing surface layer provides for stable, consistent, flat and secure ball-rolling and ball bouncing behaviour by securing the position of the playing surface layer relative to the shock absorbing layer.
  • the playing surface layer is a synthetic turf.
  • Synthetic turf may require less maintenance and is more resistant to damage than natural grass.
  • the synthetic turf is an unfilled synthetic turf.
  • Unfilled synthetic turf may not require any infill material, which improves playing consistency which might be hindered by an uneven spread of the infill material or the degradation of the infill material over time.
  • unfilled synthetic turf may not be suitable in some locations.
  • the playing surface elements each comprise a textile secondary backing layer.
  • tufts of synthetic grass may be secured to the textile secondary backing layer.
  • the textile secondary backing layer may improve the stability of the playing surface.
  • the individual surface layer elements may be rolled or stacked. This may permit fast installation and easy transport of the individual surface layer elements.

  • the shock absorbing layer elements may comprise a closed cell foam. This may have higher compressive strength than open cell foams.
  • the shock absorbing layer elements may comprise a cross-linked foam.
  • said foam is a polyethylene foam. This may provide improved resilience, shock absorption, and strength.
  • a further advantage of using a foam, in particular a polyethylene foam, is that it may be capable of retaining large volumes of water. Together with the drainage means of the base layer elements, which include voids to retain water, the base layer and the shock absorbing layer are capable of retaining water such that it can slowly drain rather than running through the temporary, relocatable, sports pitch assembly quickly, which may compromise the temporary, relocatable, sports pitch assembly and its performance.
  • the playing surface layer comprises line markings, which may differ by sport.
  • the line markings may be inlaid lines and/or tufted lines manufactured within the playing surface layer.
  • this allows for the temporary, relocatable, sports pitch assembly to be assembled independent of weather conditions, as no additional markings need to be applied upon assembly.
  • One particularly suitable foam may be a polyethylene foam. This may be inexpensive, provide good shock absorption properties, and be impervious to water or may alternatively absorb water well.
  • the foam comprises slits to accommodate for volume changes due to temperature changes.
  • temperature changes may be natural (i.e. weather-related), artificial (i.e. under-soil heating), or installation-related.
  • Providing for volume changes reduces the risk of the pitch becoming uneven due to expansion of the shock absorbing layer caused by temperature changes.
  • the shock absorbing elements comprise a non-woven fabric on a first side.
  • said non-woven fabric is attached to said first side of the shock absorbing elements.
  • said first side of the shock absorbing elements is the underside of the shock absorbing elements.
  • the non-woven fabric is configured to grip the base layer. Providing such a non- woven fabric on the underside of the shock absorbing elements opposes movement of the shock absorbing layer relative to the base layer, ensuring that the pitch remains level and that the playing behaviour of the pitch remains constant and is consistent across the pitch.

Providing such interlocking recesses and projections in adjacent shock absorbing elements may permit rapid installation. It may also facilitate repeated use of the shock absorbing elements.
  • the at least one shock absorbing element coupling device may be an adhesive.
  • An adhesive means may comprise adhesive tape, which may be double-sided adhesive tape, or a glue or a cement or a paste, or a spray or a combination of two or more of these.
  • an adhesive to removably couple adjacent shock absorbing elements to one another may provide an effective but temporary coupling the allows for separation of the adjacent shock absorbing elements. It may also permit repeated coupling and uncoupling of adjacent shock absorbing elements.
  • An adhesive may be an adhesive tape with adhesive properties that mean that it may be removed easily to uncouple adjacent shock absorbing elements from one another and does not damage the shock absorbing elements upon removal.
  • Individual shock absorbing elements may be rolled.
  • this may permit fast installation and easy transport of the individual shock absorbing elements.
